This question would apply to just about every other watch that I have ever owned. With standard leather, textile or rubber straps, the clasps only allow adjustment in about 1/4 inch increments according to the holes in the straps. If your comfort zone falls in between two holes then there's little you can do. I've been searching with little luck for a 18mm textile or maybe leather strap with a micro adjustable clasp. What after market products are available at a reasonable cost? Thanks in advance for your time.
